The latest LXPM firmware version 4.21.05 can be downloaded from the Lenovo support site, although it may not appear correctly on some machine type pages. If you encounter issues, you can still access it through the direct link provided or by using the BOMC download option. [community thread]
This is a known behavior in Windows Server 2022 where the operating system may display disk order differently than what is configured in the RAID controller. This discrepancy occurs because Windows enumerates devices based on their response time during initialization, not the RAID firmware's numbering. [community thread]
The failure may be due to using an incorrect firmware package type; ensure you are using .uxz, .exi, or signed component .zip files instead of the full bundle ZIP. Additionally, consider updating individual components using the 'multipart/form-data' method, and verify that the firmware file is not corrupted. [community thread]
